SUMMARY:Multi-color Holograms Improve Brightness in Holographic Displays
DESCRIPTION:Koray Kavaklı (Koç University), Liang Shi (Massachusetts Insti
 tute of Technology), Hakan Urey (Koç University), Wojciech Matusik (Massac
 husetts Institute of Technology), and Kaan Akşit (University College Londo
 n (UCL))\n\nHolographic displays generate Three-Dimensional (3D) images by
  displaying single-color holograms time-sequentially, each lit by a single
 -color light source. However, representing each color one by one limits br
 ightness in holographic displays.\n\nThis paper introduces a new driving s
 cheme for realizing brighter images in holographic displays. Unlike the co
 nventional driving scheme, our method utilizes three light sources to illu
 minate each displayed hologram simultaneously at various intensity levels.
  In this way, our method reconstructs a multiplanar three-dimensional targ
 et scene using consecutive multi-color holograms and persistence of vision
 . We co-optimize multi-color holograms and required intensity levels from 
 each light source using a gradient descent-based optimizer with a combinat
 ion of application-specific loss terms. We experimentally demonstrate that
  our method can increase the intensity levels in holographic displays up t
 o three times, reaching a broader range and unlocking new potentials for p
 erceptual realism in holographic displays.\n\nRegistration Category: Full
